COOKING-STOVE.

Specification of Letters Patent No. 3,939, dated March 12, 1845.

To all whom it may concern:

Be it known that I, JOHN T. DAVY, of Troy, in the county of Rensselaerand State of New York, have invented a new and useful Improvement inStoves; and I do hereby declare that the following is a full, clear, andexact description thereof, reference being had to the accompanyingdrawing, which forms a part of this specification, in which Figure 1 isa perspective view showing the front of the stove. Fig. 2 is aperspective of the back thereof. Fig. 3, N0. 1, is a horizon talsection; No. 2 is a section horizontal with the hearth plate removed,and showing the fire chamber, &c., under it. Fig. 4: is a verticalsection at the line A-B of No. 1, Fig. 3. Fig. 5 is a verticaltransverse section on the line CD of No. 2, Fig. 3.

The nature of my invention consists in conveying the smoke and heat inthe fiue in an entire sheet round the oven and rarifying the air nearthe termination thereof so as to cause a brisk draft; and in forming thestove so as to produce the greatest economy of space and use of fuel.

I construct the main body of my stove in the form of a cube, which isplaced on legs at a proper height; onto the front of this I afiix ahearth (a), one end of which extends around to one side of the stove. Arecess b) is formed in this hearth, which is deeper than that merelyused for ashes, and serves for a fire chamber; above this a hearth plate(0) is put on, which has two boiler holes in it, and which can beremoved and replaced by a gridiron for boiling; the edge of thegridiron, as well as the hearth plate, next 'to the body of the stove isturned upward as shown at (d), Figs. 1 and 4. This covers an aperturealong the front of the stove and forms a flue from the fire chamberunder the hearth into the stove, as shown by the arrow in Fig. 4. At alittle distance from the back back and passes downward on each side of acenter flue (n) hereafter to be described, the back of the stove havingtwo projections (Z) at that point to enlarge the flue; it then continuesdown flue (m), under the oven, along the bottom of the stove to thefront; it thence ascends to the bottom of the fire chamber, runs backbetween its bottom and the'oven, and then rises at the back of the firechamber, which is of corrugated metal, and heats and rarifies the air atthat point; this I deem of the greatest importance in creating a draft;it then turns back and makes its exit through the small pipe into thechimney in the usual way. A plate (0) is fixed at the point where theflue commences beside the fire chamber; this causes the flame toreverberate around the boilers and distributes the heat more equally.

The oven extends the whole size of the lower part of the stove (boundedby the flue) the back rising up behind the fire chamber, as shown in thedrawing. This construction and combination of parts makes an equaldispersion of heat all around the oven.

The top plate of the stove has four boiler holes in it at equal distanceapart.

A damper (p) is constructed at the pointwhere the pipe crosses thedescending pipe which admits the smoke and heat directly into thechimney without passing around the oven; there may also be a throttlevalve (9, Fig. 1) in the collar which checks the draft and stops theconsumption of fuel.

Having thus fully described my improvement, what I claim therein as newand desire to secure by Letters Patent, is

The turning plate (f) in combination with the grate of the fire chamber(6) for the purpose of conducting the ashes from the fire chamber above,under the grate.
